How can we import point cloud .las files from external softwares?

It used to have a documentation in this link, but went offline: [https://support.pix4d.com/hc/en-us/articles/202560049-How-to-import-a-Point-Cloud-delivered-by-an-External-Source-into-Pix4Dmapper](https://support.pix4d.com/hc/en-us/articles/202560049-How-to-import-a-Point-Cloud-delivered-by-an-External-Source-into-Pix4Dmapper)

I read something about first you need to run step 1 with original images and then import .las. But what I actually want to do is the DSM and orthomosaic from a point cloud without coordinate (sequential, only GCP).

Is possible to generate these products from such a file?

Hi,  
here there is the updated link: [Menu Process \> Import Point Cloud for DSM Generation - PIX4Dmapper](https://support.pix4d.com/hc/en-us/articles/202557789)  
Because Pix4DMapper is not meant for pure Cloud Processing (it’s Sequential Photogrammetry: Import Photos to Create Point Cloud, from which you can Generate a DSM, and only then, obtain Contour Lines), you can only import a .las file for improve the original results, but not for a Cloud-to-DSM from scratch…  
I seldom tryed that workflow with Pix4DSurvey, if you have time to download the trial version,
